Hi Nathan , I have also had a similar experience and found experiencing such thoughts very unpleasant.
You have not mentioned if anything has occured in your life recently which would have influence on your thoughts and thinking.
Do you have any other signs of a depressive illness?
Common ones are disturbed sleep, appetite and weight changes, changes in concentration, energy levels and motivation?
These may indicate depression and if you do I would recommend seeing a medical professional, a good local doctor if you have one.
